Final answer:
True, interracial marriages were banned in some parts of the U.S. until the Supreme Court's decision in Loving v. Virginia in 1967, which invalidated anti-miscegenation laws.
Step-by-step explanation:
The statement that interracial marriages were legally banned in some parts of the United States in the 1960s is true. Interracial couples faced severe legal and social sanctions for their relationships due to the prevalence of anti-miscegenation laws. It was only with the landmark Supreme Court case of Loving v. Virginia in 1967, that such prohibitions were deemed unconstitutional. Prior to this ruling, states like Virginia enforced laws such as the Racial Integrity Act, preventing marriage between individuals of different races.
The Lovings, whose marriage in Washington D.C. was not recognized in Virginia and led to their arrest, ultimately played a crucial role in the battle for civil rights, challenging Virginia's law and succeeding. Their victory eradicated the remaining miscegenation laws across the country, a significant stride toward equality, transforming social attitudes and leading to growing acceptance and prevalence of interracial unions in the United States.
